Is 120°C Oil Temperature Normal for a BMW 5 Series?

Can the ECO mode of the Avalon be turned off?

The ECO mode of the Avalon can be turned off. The method to turn it off is to enter the sport mode, press the accelerator pedal hard to accelerate, or encounter an uphill section, and the ECO mode will automatically turn off. When to enable ECO mode: ECO mode works best in congested urban traffic conditions. In such situations, strong power is not required, and the frequent stops and starts lead to higher fuel consumption. Enabling ECO mode not only reduces fuel consumption but also makes driving more comfortable. When it is unnecessary to enable ECO mode: When the car is driving at high speeds (up to 100km/h), even if ECO mode is turned on, the vehicle's computer will prioritize speed, and the ECO mode will automatically deactivate. When high torque output is needed, such as when climbing a hill, the engine computer will prioritize ensuring sufficient power to drive the vehicle, and the ECO mode will automatically deactivate. Types of ECO modes: Generally, ECO modes can be divided into two types: passive ECO driving mode and active ECO driving mode. The passive ECO driving mode mainly serves as a reminder and guidance function. The active ECO driving mode usually has a button, and once enabled, a series of driving-related settings will change. For example, the throttle opening corresponding to the same accelerator pedal depth becomes smaller (the accelerator becomes less responsive), the transmission shift logic becomes more focused on fuel efficiency (shifting up earlier), and some vehicles may also adjust the air conditioning output power, etc.

Can Changing Spark Plugs Save Fuel?

Replacing spark plugs can save fuel and reduce consumption. If a spark plug is damaged, it can directly cause issues such as electrical leakage in the vehicle's ignition system, increased fuel consumption, decreased power, and most importantly, difficulty in ignition, affecting the normal operation of the vehicle. Severe erosion of the spark plug, such as scarring, damage, or melting and erosion of the electrode, indicates that the spark plug is damaged and should be replaced. Location of Spark Plugs: Spark plugs are installed on the side or top of the engine. In earlier models, spark plugs were connected to the distributor via ignition wires. However, over the past decade, most car engines have been modified to connect the ignition coil directly to the spark plug. Replacement Interval for Spark Plugs: Under normal maintenance conditions, spark plugs should be replaced every 40,000 to 60,000 kilometers. However, this may vary depending on the brand and engine type, so it's advisable to follow the manufacturer's manual. Typically, platinum spark plugs should be replaced at 40,000 kilometers, standard nickel alloy spark plugs at 20,000 kilometers, and iridium spark plugs at 60,000 to 80,000 kilometers.

What is the purpose of highway laser lights?

The function of laser lights on highways is to provide alerts and warnings. Here are the detailed explanations: 1. Laser lights can help drivers avoid fatigue. The green laser is a warning laser light on highways designed to prevent fatigue driving. It has high brightness and long range, and can effectively stimulate the driver's brain through changes in light, thereby alleviating visual fatigue caused by monotonous driving conditions during long nighttime drives. 2. Green laser lights create a beam network. Green laser lights form an interlaced network of beams in the air above the direction of oncoming traffic, without obstructing the driver's view. Together with strobe lights and high-pitched alarms, they create a tripartite warning system of sound, light, and electricity, stimulating the driver's senses and enhancing driving safety awareness. The effect is particularly noticeable during nighttime, rain, snow, fog, and other adverse weather conditions.

Can You Practice Driving in the Snow?

You can practice driving in the snow, but it is necessary to maintain a proper speed and pay attention to details when starting and braking. Precautions for Starting: When igniting and starting, avoid wheel spinning. Remove the snow around the vehicle and tires beforehand, especially the snow on the front windshield to ensure good visibility for the driver. To prevent fogging caused by temperature differences, it is advisable to keep a dry cloth inside the car. Precautions While Driving: During normal driving in snowy conditions, react and brake earlier than usual. The friction coefficient on icy or snowy roads is only 0.1 to 0.2, which significantly increases the braking distance. Only by reacting early can you effectively avoid accidents. Use low gear for both uphill and downhill driving, and avoid shifting gears midway. When going uphill, be careful not to stall, as it can be difficult to start again. When going downhill, absolutely avoid coasting in neutral. Precautions for Braking: Whether the vehicle has ABS or not, do not shift to neutral. Instead, use the engine's traction to slow down. For vehicles with ABS, press the brake while controlling the direction, and avoid sudden steering. For vehicles without ABS, use the manual intermittent braking method to stop.

How to Properly Control the Clutch in Subject 2?

To control the clutch in Subject 2, mastering the semi-engaged state is essential. The semi-engaged state can be simply judged through the following aspects: 1. Vehicle vibration: When reaching the semi-engaged state, the vehicle will vibrate, and you can feel it by placing your hands on the steering wheel. Especially on a slope, when the clutch is lifted to the semi-engaged state, the car will have a tendency to move forward. At this point, hold the position, gently apply some throttle, and start smoothly. 2. Foot sensation: When you notice a change in the engine sound, you will also feel a slight resistance against your foot on the clutch pedal. 3. Observe the tachometer: When you see a noticeable drop in the tachometer, you can also determine that the car has reached the semi-engaged state.

What Causes the Dripping Sound After Engine Shutdown?

Engine has dripping sound This is the sound of thermal expansion and contraction. When driving, the exhaust pipe gets very hot, and after parking and turning off the engine, the exhaust pipe cools down, causing the metal to expand and contract with heat, thus producing this sound. Below is relevant information about automobile exhaust pipes: 1. Introduction: The automobile exhaust bellows, also known as the automobile exhaust pipe flexible hose, is installed in the exhaust pipe between the engine exhaust manifold and the muffler. It provides flexible connection for the entire exhaust system, thereby reducing vibration and noise, facilitating installation, and extending the service life of the exhaust muffler system. 2. Classification: Exhaust pipes are generally divided into: standard original pipes, backpressure pipes, semi-backpressure pipes, and straight-through pipes.
